GAS-BURNER.

To all 107mm t may concern.'

Beit known that I, GEORGE W. CALEF, a citizen of the United States, and a resident of the city of Boston, in the county of Suffolk and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Gas-Burners, of whichlthe followingr is a full, clear, and exact specification. K

This invention has for its object the construction of a comparatively inexpensive, ecient and easily adjusted gas burner for use in the fire pots of kitchen ranges and the like.

In carrying my invention into effect, I provide a hollow member or header with means for supplying it with a mixture of burning gas and air, having a plurality of perforated tubes projecting from the header to act as the burners proper, yand adapt each tube for being closed at will in order to restrict the number of lame-emitting tubes to two or even one.

.ln the drawings forming part of this specification, Figure l is a side sectional elevation oi a gas burner embodying my improvements. Fig. 2 is a cross Vsect-ion of the saine on the line l-lin Fig. l.' Fig. 3 is a cross section on the line 2 2 in Fig. l.

's a longitudinal section of the gasandvair supplying means.

T he header consists of a metal box 3 having an open side closed by a cover 4 conlined thereto by suitable means, as stove bolts This bon1 and cover are preferably formed by casting, and has the inne' surface of its side (l provided with several bosses 7, preferably four in number. A.. hole is made through each boss and, these holes are suitably tapped for the air-tight admission of the threaded ends ot' tubes `9, 1.0 andrll. T he tube ll is located close to the top o the header, and is provided with a row ot burner holes l2 along the'top-inost .Line of its pem ripl'icry, as shown in Fig. f

Lower down but spared from each other are two other tubes l!) parallel with the first and 0In substantially the same length, each tube l0 having two rows of holes 13 and 14e along its outermost section.

ln line with each tube l0. il within the header., is a slidabie stein 16 passing through a suitable pushing l? to the exterior of the l'ieader-cever el. The outer end ol each stem 16 is ixireferably bent upward through a guide-slot 19, and its inner end is provided Specification of Letters-Patent.

with a cap 20 faced with a layer of yielding material, preferably asbestos 2l.

he burning gas is supplied through a tube 22 into a passage 23 into which it draws a certain quantity of air through the air holes 24, the mixture passing` on through a tube 25 into the header, taking in with it an added proportion of air through the air holes 26. From theheader the thoroughly oxygenized gas' passes to the tube l0, 1l which may happen to be open, and being ignited at the holes l2, lland 14, it burns with a remarkably perfect combustion and with great heat." It' but comparatively little heat is desired in the stove, and that immediately beneath its top, both caps 20 controlling the tubes l() are moved into engagement with the open ends of the latter, and, the gas being thereby shut off therefrom, the flames vill issue from the top tube 1l alone.

Should a maximum supply of heat be desired, all three ol the tubes l0, ll are opened by the withdrawal of their caps 20, and all emit flames. f

Ordinarily a kitchen range provided with a water-front for heating the water in a boiler, and opposite thereto is a partition separating the lire pot from fthe oven 'As indicated in Fig. 2, the llames issuing from the holes 13, lll. will moet squarely against the sides of the lire pot, one ol which sides will be the oven-partitionand the other willl be the water-trout. lt' it is desired to heat the oven without heating the water in the boiler, the tube l() at the Watent'rmit side will be closed by its cap 2l) and the opposite' tube only, or the latter and the tube ll, will be permitted to supply heat.

Ur, it' het water is wished without heating the oven, then the other tube l() will be closed and the 'former closed on.e.will be opened.

By entirely closing both tubes' lll, and sliding the cap 2() of the tube llV almost into contact with the latter, just enough can be supplied to the tube il to maintain a minimum amount ot warmth to the stove.

ln this way, a burner providral whirh is capable ot adjustment through a wide range of heat-umts, and also tor supplying.

The burner should be arranged in theflire pot with the cover adjacent the stove. door in order to permit or" convenient access'to the stems 16.

'header adapted toreceive a justed into contact with thetube-ends 'the pressureof the gas within'the header aids in binding them gas-tight against the same.

2. A gas burner comprising a hollow header adapted to receive a supply of burning gas, a plurality of burnerptubes communicating with the interior of the header,

' a cap for the inner end of each tube, a stem supporting each, cap slidab'ly supported b a wall of the header and extended through the same to the exterior thereof, each stem having means for rendering its passage to the exterior gas-tight, the outer end. of each and laterally `spaced stembeing-bent upward, and a slotted guide slidably receiving each upward-bend.

3. A gas burner comprising a header having means for supplying it with a burning gas, andthree burner tubes projecting from and communicating. with the interior of said header, the tubes being parallel, one thereof being near the top of the header and the other two being lower down and laterally spaced, the latter tubes having each two rows of jet-holes along its outermost periphery.

4. A gas burner comprising a hollow header having means for supplying it with a burning gas, vand three burner tubes projecting from and communicating with the interior thereof, the tubes being parallel, one thereof being near the top of the header and having jet-holes along its topmost surface, and the other two being lower down dislplosed jet-holes.
